A preliminary study has demonstrated the feasibility of an experimental molecular biomarker to combine with PET imaging for reliably showing the extent of prostate cancer. Along the way, researchers found that the technique can also catch some cancers hidden to pathologists.&nbsp;

Mentally demanding activities may be neuroprotective and an important element for maintaining a healthy brain into late adulthood, according to findings published in Restorative Neurology and Neuroscience.

A robust, population-based study has revealed that, from 2001 through&nbsp;2009, the use of PET imaging swelled among patients with resected non&ndash;small-cell lung cancer (NSCLC) and colorectal cancer (CRC).

Gadolinium chelate administration is largely unnecessary for imaging pediatric tumors when performing MRI or combined&nbsp;PET/MR scans, according to a recent study published by&nbsp;the Journal of Nuclear Medicine.

Scientists from Japan, Russia and the U.S. have discovered four new chemical elements that, taken together, complete the seventh period of the periodic table of elements. And the first area of human endeavor to find a practical use for the expanded knowledge may be nuclear medicine.

Researchers at the University of Toronto have found that pediatric epilepsy patients imaged prior to neurosurgery with a new protocol have a greater chance of being seizure-free following the operation than those imaged using an older protocol.

CMS has finalized its proposal of last September not to pay for PET scans using the sodium-fluoride radiopharmaceutical NaF-18, which the agency says still lacks evidence backing it as &ldquo;reasonable and necessary&rdquo; in the diagnosis and treatment of cancer that has metastasized to the bones.&nbsp;

PET/CT performed after the administration of both F-18 sodium fluoride (NaF) and F-18 fluorodeoxyglucose (FDG) beats both whole-body MRI and bone scintigraphy on accuracy in evaluating metastasis to bones from advanced breast and prostate cancers, according to a preliminary study running in the December issue of The Journal of Nuclear Medicine.

For women who underwent silicone implant reconstruction after breast cancer treatment, enlarged internal mammary lymph nodes (IMLNs) can be a cause for concern. However, a new study published in the November issue of&nbsp;Radiology&nbsp;has demonstrated that in most cases, IMLNs spotted on MRI are benign.
